Match each example or description with the corresponding level of protein structure. only found in proteins composed of more refers to the way several different the overall 3-D shape the sequence of amino acids in the polypeptide chains 6 ted sheet of a polypeptide or than one polypeptidetogether to form the polypeptide chains fit protein final protein results from the bending results from hydrogen bonds between polar Ala-Gly-Tyr-Lys-Met and folding of a polypeptiderepeated pattern of chain that occurs due to a variety of interactions between the amino acid side chains coiling or folding within a polypeptide chain alpha-helix groups in the polypeptide backbone Trp-Phe primary structure secondary structure quaternary structure tertiary structure ResetExplanation / Answer
I)The structure of protein can be described from basic to complex and final level. It starts with primary structure and ends to form Quarternary structure.
ii)Proteins are composed of amino acids.
iii)The amino acids may form alpha helix or beta sheet structure and are linked to each other through hydrogen bonds
iv)Complexity of a protein begins with several interactive forces occurring in the polypeptide chain between side chains of amino acids to give three dimensional shape of the protein. Complexity is necessary for giving the protein it's functionality feature. It allows twisting and bending so as to reach more stability and less energy state.
V)At times more than one polypeptide chain occurs in a protein and they interact with each other to form the final stage of functional protein.
vi) tertiary structures talk about interactions within polypeptide chains whereas quarternary structure describes interactions occurring between the polypeptide chains.
On the basis of the above discussion let's take up the question.
The sequence of amino acids in the polypeptide chains will be put under the category of primary structureml. Ala-Gly-Tyr-Lys-Met-Trp-Phe is also representing primary structure. This is in context with ii) point
Alpha helix, beta pleated sheet, results from hydrogen bonds between polar groups in the polypeptide backbone- they represent secondary structure as described under iii) point
The overall 3D shape of a polypeptide chain or protein, results from the bending and folding of a polypeptide chain that occurs due to a variety of interactions between the amino acid chains, repeated pattern of coiling or folding within a polypeptide chain- represents tertiary structure as given under point iv)
Only found in proteins composed of more than one polypeptide chain and refers to the way several different polypeptide chains fit together to form the final protein- describes Quarternary structure as given under v) point
